低压电器常用控制方式

Common Control Methods for Low-Voltage Apparatus

低压电器的控制是电工电子学习中比较困难的一部分,也是容易出错的一部分。利用电器控制电路图能直观形象地理解控制原理,因此以三相异步电机为控制对象,介绍了几种常用的控制思路,如像自锁、联锁、顺序启动控制、顺序停止控制、多地控制等。这几种思路组合起来可以实现对三相异步电机的各种控制。

The control of low-voltage electrical appliances is a difficult and error-prone part of learning electrical engineering.The use of electrical control circuit diagram can intuitively understand the control principle.Therefore,taking the three-phase asynchronous motor as the control object,several commonly used control ideas are introduced,such as self-locking,interlocking,sequential start control,sequential stop control,multi-place control,etc.The combination of these ideas can realize various controls of three-phase asynchronous motors.
